How to Handle Exceptions in PL/SQL Code

In PL/SQL, you can handle exceptions using the EXCEPTION block. This block allows you to gracefully manage errors and prevent the application from crashing.

To handle exceptions in PL/SQL code, you need to:

1. Identify the Exception: Use the EXCEPTION block to specify the type of exception you want to handle. This can be done using predefined exceptions or custom exceptions.
2. Handle the Exception: Within the EXCEPTION block, you can write code to manage the error, such as logging the error message, rolling back transactions, or providing a user-friendly error message.
3. Raise the Exception: After handling the exception, you can choose to raise it again if necessary, re-throwing the error to be caught at a higher level in the program.

By effectively handling exceptions in your PL/SQL code, you can ensure the stability and reliability of your application, improving user experience and overall system performance.
